Your existing mortgage balance moves to the new property at your original low rate. No refinance, no new underwriting.
If your new home costs more, PortKey originates a gap loan at current market rates to cover the difference.
You make a single monthly payment. We handle the split. The blended rate is almost always lower than a full refinance.
